I have no idea why some think these were Americans. Likely they were foreign nationals whose lives (and families’ lives) would be endangered by knowledge that they worked for America.
But it’s still a good question not asked by anyone in the MSM.
For the most part, the MSM is owned by the enemy. Why would they ask a question that would damage their interests?
I am astonished that sentient freepers are still incredulous about the behavior of the so-called MSM.
